Abstract
Filarial adult were found in the intermuscular connective tissue of the peritracheal and mandibular region of the Taiwan monkey(Macaca cyclopis). The microfilariae in the peripheral blood demonstrated a marked nocturnal periodicity with a peak between 2100-0100 hours and a low diurnal minimum between 900 and 1300 hours. Staining the microfilaria by various stains demonstrated differences in size. No development of microfilariae was detected in the Culex fatigans, Culex tritaeniohyncus, Aedes albopictus, Anopheles minimus, Armigeres subalbatus or Mansonia uniformis mosquitoes.
